如何将多个图像和文本合并为单个图像？ [英] How to merge multiple images and text into single image?

问题描述

我在div中有多个PNG图像，这些图像是PNG，并根据他/她选择的自定义选项呈现为用户的单个图像。此外，添加文本也可以作为其他功能启用，它允许带有文本的div添加到这些图像的上方。

I have multiple PNG images inside a div, those images are PNG and presents as single image for user depending on custom options he/she has selected. Also, adding text is also enabled as other feature, which allows a div with texts to add above of those images.

现在我想生成带有这些图像的图像和文本相结合，维护字体系列和文字大小。

Now i want to generate a image with those multiple images and text combined, maintaining the font-family & size of text.

例如。界面上显示的图像与图像和文本的组合。 （它设法用css定位出现）

这是由下面两张图片和文字组成的

For eg. the image that appears on interface with combination of images and text. (It's managed to appear with css positioning) Where as this is made of two images below and text

这是我尝试拍摄的照片：create-image.php文件

This is what i tried taking images : create-image.php file

<?php
createimageinstantly();
function createimageinstantly($img1='',$img2='',$img3=''){
    $x=$y=1000;
    header('Content-Type: image/png');
    $targetFolder = '/gw/media/uploads/processed/';
    $targetPath = $_SERVER['DOCUMENT_ROOT'] . $targetFolder;

    $img1 = $targetPath.'img1.png';
    $img2 = $targetPath.'img2.png';
    $img3 = $targetPath.'img3.png';

    $outputImage = imagecreatetruecolor(1000, 1000);

    $first = imagecreatefrompng($img1);
    $second = imagecreatefrompng($img2);
    $third = imagecreatefrompng($img3);

    imagecopy($outputImage,$first,0,0,0,0, $x, $y);
    imagecopy($outputImage,$second,0,0,0,0, $x, $y);
    imagecopy($outputImage,$third,0,200,-200,0, $x, $y);

    imagepng($outputImage, $targetPath .round(microtime(true) * 1000).'.png');

    imagedestroy($outputImage);
 }
?>

但是这给了我整个黑色的图像

But this gives me whole black colored image

另外，我需要在最终生成的图像上混合文字

Also, i need to mix with text on the finally generated image

已编辑：

• jpg图片已更改为png

• jpg images changed to png

imagecopymege 更改为 imagecopy

                // set background to white
                $white = imagecolorallocate($outputImage, 255, 255, 255);
                imagefill($outputImage, 0, 0, $white);

                $first = imagecreatefrompng($img1);
                $second = imagecreatefrompng($img2);
                $third = imagecreatefrompng($img3);

                //imagecopyresized ( resource $dst_image , resource $src_image , int $dst_x , int $dst_y , int $src_x , int $src_y , int $dst_w , int $dst_h , int $src_w , int $src_h )
                imagecopyresized($outputImage,$first,0,0,0,0, $x, $y,$x,$y);
                imagecopyresized($outputImage,$second,0,0,0,0, $x, $y,$x,$y);
                imagecopyresized($outputImage,$third,200,200,0,0, 100, 100, 204, 148);

                imagepng($outputImage, $targetPath .round(microtime(true)).'.png');

                imagedestroy($outputImage);
            }
        ?>

输出图像

And the output image

推荐答案

我用这种方式实现了它，

And i achieved it this way,

使用这3张图片，img1.png，img2.png，img3.png

Used these 3 images, img1.png,img2.png,img3.png

和 create-image.php file

 <?php
        createimageinstantly();
        //$targetFolder = '/gw/media/uploads/processed/';
        //$targetPath = $_SERVER['DOCUMENT_ROOT'] . $targetFolder;
        //$img3 = $targetPath.'img3.png';
        //print_r(getimagesize('http://www.vapor-rage.com/wp-content/uploads/2014/05/sample.jpg'));
        function createimageinstantly($img1='',$img2='',$img3=''){
            $x=$y=600;
            header('Content-Type: image/png');
            $targetFolder = '/gw/media/uploads/processed/';
            $targetPath = $_SERVER['DOCUMENT_ROOT'] . $targetFolder;

            $img1 = $targetPath.'img1.png';
            $img2 = $targetPath.'img2.png';
            $img3 = $targetPath.'img3.png';

            $outputImage = imagecreatetruecolor(600, 600);

            // set background to white
            $white = imagecolorallocate($outputImage, 255, 255, 255);
            imagefill($outputImage, 0, 0, $white);

            $first = imagecreatefrompng($img1);
            $second = imagecreatefrompng($img2);
            $third = imagecreatefrompng($img3);

            //imagecopyresized ( resource $dst_image , resource $src_image , int $dst_x , int $dst_y , int $src_x , int $src_y , int $dst_w , int $dst_h , int $src_w , int $src_h )
            imagecopyresized($outputImage,$first,0,0,0,0, $x, $y,$x,$y);
            imagecopyresized($outputImage,$second,0,0,0,0, $x, $y,$x,$y);
            imagecopyresized($outputImage,$third,200,200,0,0, 100, 100, 204, 148);

            // Add the text
            //imagettftext ( resource $image , float $size , float $angle , int $x , int $y , int $color , string $fontfile , string $text )
            //$white = imagecolorallocate($im, 255, 255, 255);
            $text = 'School Name Here';
            $font = 'OldeEnglish.ttf';
            imagettftext($outputImage, 32, 0, 150, 150, $white, $font, $text);

            $filename =$targetPath .round(microtime(true)).'.png';
            imagepng($outputImage, $filename);

            imagedestroy($outputImage);
        }
    ?>

结果图片为

And the result image is
